Important Pre-Assembly Notes

1. Airframe material: EPO foam. Do NOT use CA glue, acetone or aggressive cleaners �� these dissolve foam. Use foam-safe glue only if repairs needed.
2. Required equipment (NOT included):
   • 4~5 channel transmitter + receiver (5ch recommended for reverse thrust function)
   • 4S 14.8V LiPo battery: 1800�C2200mAh, ��35C, XT60 plug
   • LiPo balance charger for 4S packs
3. Always power on transmitter FIRST (throttle stick fully down), then connect aircraft battery.
4. Official manual download: https://www.freewing-model.com/download/freewing-64mm-bac-lightning-jet-manual.pdf

Step 1: Unpack & Inventory All Parts

• Fuselage (EDF motor, 40A ESC, servos, fixed landing gear pre-fitted)
• Left / Right Main Wings
• Left / Right Vertical Stabilizers
• Full-flying Horizontal Stabilizers
• Control pushrods, clevises, retaining screws
• Canopy, battery hatch, foam tape/Velcro
• Instruction sheet

Step 2: Install Horizontal Stabilizers (All-Moving Tail)

1. Flip fuselage upside down. Locate horizontal tail mounting slots at rear fuselage.
2. Route elevator pushrod into fuselage tail channel.
3. Slide left & right horizontal stabilizer pivot shafts into fuselage mount.
4. Attach pushrod clevis to elevator horn. Center the stabilizer surface perfectly neutral.
5. Secure with supplied small locking screws (do not over-tighten; easy to strip foam/plastic).
6. Repeat for opposite horizontal stabilizer.

Step 3: Mount Vertical Stabilizers

1. Carefully route rudder servo extension wire out of fuselage tail opening.
2. Plug servo wire connector, push connector into cable routing channel.
3. Slide vertical fin into fuselage tail saddle.
4. Connect rudder pushrod clevis to rudder control horn, set rudder to neutral position.
5. Secure vertical stabilizer using provided screws. Fit both left & right fins.

Step 4: Install Main Wings

1. Insert the carbon fiber wing spar through fuselage wing mount tube.
2. Plug in aileron servo wiring extension between wing and fuselage harness. Secure connector inside wing root cavity.
3. Slide left wing onto carbon spar, align wing root flush with fuselage.
4. Attach aileron pushrod clevis onto aileron horn; set ailerons neutral.
5. Lock wing root using fixing screws on bottom fuselage. Complete both wings.

Step 5: Final Airframe Check

• Double-check all pushrods: no binding, all control surfaces move freely full travel.
• Confirm all wiring is tucked away �� avoid pinching wires when fitting wings/tail.
• Fit the clear canopy.

Step 6: Install Receiver & Wiring Setup

1. Open battery hatch; place receiver in forward fuselage radio compartment. Secure with double-sided foam tape.
2. Plug all servo leads and ESC throttle lead into receiver channels:
   • CH1: Aileron
   • CH2: Elevator
   • CH3: Throttle (EDF fan)
   • CH4: Rudder
   • CH5: Reverse Thrust (assign channel if your radio supports reverse)
3. Route receiver antenna outside foam for best signal; keep antenna clear of ESC power wires.

Step 7: Radio Binding & Pre-Flight Electronic Test

1. Turn ON transmitter, throttle stick all the way down.
2. Bind receiver to your radio following your transmitter manual.
3. Connect 4S LiPo battery (XT60). Wait for ESC beep confirmation sequence.
4. Verify control directions:
   • Right stick right �� right aileron up
   • Pull elevator back �� elevator trailing edge up
   • Right rudder command �� nose turns right

Reverse servo direction inside radio menu if controls work backwards.

Step 8: EDF Fan Spin Test (SAFETY FIRST!)

1. Slowly advance throttle to low setting, confirm fan spins forward (normal thrust).
2. If fan rotates backwards: swap any two motor wires between motor and ESC.
3. Test reverse thrust function (if equipped): activate assigned switch, fan reverses rotation.

Step 9: Center of Gravity (CG) Setup �� CRUCIAL FOR FLIGHT

• Balance aircraft without battery first, then insert LiPo pack.
• Slide battery forward/back inside battery tray until jet balances level.
• Secure battery using supplied Velcro straps inside battery compartment.

Battery bay dimensions: L200 �� W54 �� H38 mm

Step 10: Control Travel (Dual Rates Recommended)

• Aileron: 18�C22mm total throw
• Elevator: 20�C24mm total throw
• Rudder: 16�C20mm total throw
  Enable Expo (25�C30%) for smoother low-speed handling.

Critical Safety Warnings

Short clear answer:

What servo work YOU actually do:

1. Plug the pre-made servo extension connectors (wing/tail servos plug into main fuselage harness when fitting wings and stabilisers)
2. Attach the clevis ends of pushrods to control horns
3. Centre control surfaces and adjust pushrod length for neutral trim

Things you don��t have to do:

• Screw servos into foam
• Run servo wires through the airframe
• Mount servo arms

Only the Kit / KIT version comes with loose servos you install from scratch. PNP = all power & servo hardware pre-fitted at factory.
